AS Bonomo, S Desidera, S Benatti, F Borsa… - Astronomy & …, 2017 - aanda.org
We carried out a Bayesian homogeneous determination of the orbital parameters of 231
transiting giant planets (TGPs) that are alone or have distant companions; we employed …

TESS transit timing of hundreds of hot Jupiters

ES Ivshina, JN Winn - The Astrophysical Journal Supplement …, 2022 - iopscience.iop.org
We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

The orbit of WASP-12b is decaying

SW Yee, JN Winn, HA Knutson, KC Patra… - The Astrophysical …, 2019 - iopscience.iop.org
WASP-12b is a transiting hot Jupiter on a 1.09 day orbit around a late-F star. Since the
planet's discovery in 2008, the time interval between transits has been decreasing by 29±2 …

The Apparently Decaying Orbit of WASP-12

KC Patra, JN Winn, MJ Holman, L Yu… - arXiv preprint arXiv …, 2017 - arxiv.org
We present new transit and occultation times for the hot Jupiter WASP-12b. The data are
compatible with a constant period derivative: $\dot {P}=-29\pm 3$ ms yr $^{-1} $ and $ P/\dot …

Visible-light Phase Curves from the Second Year of the TESS Primary Mission

I Wong, D Kitzmann, A Shporer, K Heng… - The Astronomical …, 2021 - iopscience.iop.org
We carried out a systematic study of full-orbit phase curves for known transiting systems in
the northern ecliptic sky that were observed during Year 2 of the TESS primary mission. We …

Decaying orbit of the hot Jupiter WASP-12b: Confirmation with TESS observations

JD Turner, A Ridden-Harper… - The Astronomical …, 2021 - iopscience.iop.org
Abstract Theory suggests that the orbits of some close-in giant planets should decay due to
tidal interactions with their host stars. To date, WASP-12b is the only hot Jupiter reported to …

ExoClock Project. II. A large-scale integrated study with 180 updated exoplanet ephemerides

A Kokori, A Tsiaras, B Edwards… - The Astrophysical …, 2022 - iopscience.iop.org
The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

The continuing search for evidence of tidal orbital decay of hot Jupiters

KC Patra, JN Winn, MJ Holman, M Gillon… - The Astronomical …, 2020 - iopscience.iop.org
Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot
Jupiter for which orbital decay has been directly detected is WASP-12, for which transit …

TESS Revisits WASP-12: Updated Orbital Decay Rate and Constraints on Atmospheric Variability

I Wong, A Shporer, S Vissapragada… - The Astronomical …, 2022 - iopscience.iop.org
After observing WASP-12 in the second year of the primary mission, the Transiting
Exoplanet Survey Satellite (TESS) revisited the system in late 2021 during its extended …

HST hot-Jupiter transmission spectral survey: evidence for aerosols and lack of TiO in the atmosphere of WASP-12b

DK Sing, A Lecavelier des Etangs… - Monthly Notices of …, 2013 - academic.oup.com
Abstract We present Hubble Space Telescope (HST) optical transmission spectra of the
transiting hot-Jupiter WASP-12b, taken with the Space Telescope Imaging Spectrograph …
